My research interests are centered in three key areas: closed-loop deep brain stimulation for Parkinsons Disease (PD); closed-loop stimulation for epilepsy; and brain-machine interactive control of fast movements.
With respect to closed-loop deep brain stimulation (DBS) for Parkinsons Disease, my focus is on the modeling of basal ganglia (in health and PD), the modeling effect of DBS, and feedback control design of DBS strategies.
Seizure detection from invasive EEG signals, and seizure foci localization from invasive EEG signals are central to analysis of closed-loop stimulation of epilepsy.
Brain-machine interactive control of fast movements entails the modeling of cerebro-cerebellar regions from human and primate data, as well as optimization the design of a decoder-compensator.
